Land is stuck in corporate farms or held by generational families that haven't yet sold out. The government than subsidizes the crops grown making it a incentive to grow certain crops without bearing the risk of bad weather or drought. This has down falls because of soil erosion and bad farming practices. After the seed is bought, chemicals applied gas in the machine, repairs and new million dollar equipment upgrade, plus irrigation expense if you are so wealthy to afford, farming is a wash for the little guy. Cash crops go to fuel cars and feed livestock. Farmers with 100 of acers are the ones putting kids through public schools, upgrading the fire station and library, and paving the roads in some states. Just be cause they haven't given up the generational farm stead. Even after the local government tries to tax them out of their home and property.
